                   down to the oceans

  

This time am going to write about four more oceanic features.

Continental shelf

This a gently sloping area that borders a continent. It extends offshore from almost nothing to 1000 miles wide and about 180 meters deep.


Continental slope

This a very steep slope that drops down from the continental shelf. It could be 12 miles wide and 10000 feet deep.


Abbysal plane 

This is the most level surface of planet Earth. If sediment collects over the rough parts of the ocean floor we call it an abbysal plane.


Mid ocean ridges

these are continuous mountain chains that can be found in every big ocean. They represent more than 20 percent of Earth’s surface.

And with that, I complete DOWN TO THE OCEANS. please keep visiting my blog.

  Keeping an outdoor fish pond                                                               I am going to write about how to keep an outdoor fish pond today, based on my experience.   Furnishing a pond First the new concrete pond has to be cleaned properly (if the pond is very freshly built, add some water and some natural decaying matter and leave for about 2 weeks, as fresh cement can be poisonous to fish). Then a layer of bottom substrate can be added. Then fill the pond with water. After it has settled, you can start with the other things. A pond can be furnished with aquatic plants, rocks and maybe dead coral pieces that have washed to the shore. You can also keep a non-aquatic wine like plant as it might creep its way into the pond and make a forest appe...
